A source tells me that Williams will appear in this season’s 10th episode, yet she will not cross paths with on-screen hubby Collins, who was booked for a multi-episode run. ‘Private Practice’ airs Thursdays at 10/9c.

Williams is a three-time Emmy nominee for her work in the TV-movies ‘Adam’ and ‘Baby M’ and a guest turn on ‘Frasier.’ Her film credits include the supernatural spooker ‘Poltergeist.’
